lution, adapted to combine with the acid to form carbonic acid gas underpressure, the ingredients being separated from each other when the tankis in an upright position, and brought into union by the inversion orinclination of the tank.

The invention has for its object to provide an extinguisher of thisclass of large capacity capable of dealing with fires of considerablemagnitude, and therefore of greater w ight than the ordinary handchemical fire extinguishers.

' The invention is embodied in a chemical fire extinguisher comprising atank, carrying wheels mounted on the tank, and adapted for use intransporting the same, and means for storing a hose upon the exterior ofthe tank between the wheels, the relative arrangement of the tank andwheels being such that the tank may rest upon its foot -in an uprightposition with the wheels elevated above the supporting surface, or maybe inclined to give the wheels a bearing on the supporting surface andpermit the transportation of the apparatus without mixing the contentsof the tank, the tank being adapted to be further tipped or inclinedsufficiently to cause the mixture of the contents and the generation ofgas under pressure.

Of the accompanying drawings forming a part of this specification,Figure 1 represents a front elevation of a fire extinguisher einbodyingmy invention. Fig. 2 represents a side elevation of the same, the tankbeing shown in an upright positionin Figs. 1 and, 2. Fig. 3 represents aview similar to Fig. 2, one of the wheels being removed and the tanktipped to cause the mixture of its contents. Fig. 4 represents atransfer section of the tank without its carrying wheels.

The same numerals of reference indicate the same parts in all thedrawings.

of suitable ingredients such as sulfuric acid and a soda solution, thetank being provided with a hose 13 suitably connected with the headportion of the tank.

14:, 14; represent carrying wheels which are suitably connected with thetank, the hubs of the wheels being preferably mounted and rotated onaxle arms 15, 15, affixed to opposite sides of the tank and projectingin. opposite directions therefrom substantially in the central verticalline of the tank. The relative arrangement of the tank and wheels issuch that when the tank is in an upright position, as shown in Figs. 1and 2, its base or 1 foot 16 will rest upon a supporting surface orfloor, the wheels being raised from said surface so that they areinoperative. When the tank is in this position, its gas generatingingredients are held separate from each other,

so that the apparatus is inoperative, or in other words, is in aninoperative position. W hcn the tank is to be used, it is tipped fromits inoperative position either forward or backward to an inclinedposition such as illustrated by full lines in Fig. 3, this being theoperative position of the tank, because it causes the escape of the acidelement and its mixture with the soda solution. The head portion of thetank is provided with a suitable abutment adapted to bear on thesupporting surface when the tank reaches its operative position, saidabutment, as here shown, being an arm 18 projecting from the front sideof the head portion of the tank. Thetank is maintained in itsinoperative po* sition by the weight of its contents, and by the bearingof the abutment 18, and of the wheels 1% on the supporting surface.

if it is desired. to transport the extinguisher for any considerabledistance before making it operative, the tank is first tipped onlysufficiently to move the wheels into contact with the supporting surfacewithout mixing the contents of the tank, as indicate l by dotted linesin Fig. 3. hen the tank is in this position it may be readilytransported, the wheels running freely on the supporting surface.Suitable handles 19 are provided at the front of the tank between thewheels to ing the hose 13, said means, as here shown,

including a bracket 21 attached to the head portion of the tank, andadapted to support a plurality of convolutions of the hose, a pair ofside arms 22, 22, projecting from the tank below the bracket 2]., a pairof spring clips 23 projecting from the tank below the side arms 22, andadapted to engage the base portion of the hose nozzle 24, and an eye orsocket 25 attached to the tank below the clips 23, and adapted toreceive the tip of the nozzle. The side arms 22 confine the convolutionsof the hose against outward movement toward the wheels, as indicated inFig. 1..

It will be seen that when the use of the extinguisher becomes necessary,the tank may be readily swung to the position shown by dotted lines inFig. 3, and moved to the place where its use is required, and thenquickly moved to its operative position shown in full lines in Fig. 3,this causing an immediate generation of gas, the extinguisher beingready for use by the time the hose can be uncoiled and extended. Afteruse, the tank may be readily returned to the position shown in Figs. 1and 2, and again charged.

The axle arms 15 are attached to the tank by means of segmental plates26, suitably affixed to the bases of the axle arms, and riveted to thetank. The hose-confining arms 22 are preferably integral parts of theplates 26, as shown in Fig. 4, provision being thus made for attachingthe axle arms and. the hose-confining arms at one operation, and forreducing the number of separate parts to the minimum.

I claim:

1.. A lire extinguisher comprising a tank and carrying wheelsconstituting a support on which the tank is adapted to swing for ward orbackward from an upright inoperative position to an inclined operativeposition, said tank having a the circumference of the Wheels.

2. A fire extinguisher comprising a tank, and carrying wheels mountedsubstantially in the line of the center of the tank and con stituting asupport on which the tank is adapted to swing from an uprightinoperative position to an inclined operative position, the foot of thetank projecting outside the circumference of the wheels, whereby whenthe tank is in an upright position, the wheels are elevated above thesurface which sup.- ports the extinguisher.

8. A fire extinguisher comprising a tank and carrying wheelsconstituting a support on which the tank is adapted to swing forward orbackward from an upright inoperative position to an inclined operativeposition, said tank having a base or foot outside the circumference ofthe wheels, the head of the tank having an abutment adapted to bear on asupporting surface when the tank is in its operative position.

4. A fire extinguisher comprising a tank and carrying wheelsconstituting a support on which the tank is adapted to swing forward orbackward from an upright inoperative position to an inclined operativeposition, said tank having a base or foot outside the circumference ofthe wheels, hose-storing members at the rear side of the tank, and anabutment at the front side of the tank adapted to bear on a supportingsurface when the tank is in its operative position.

5. A fire extinguisher comprising a tank, segmental plates attached. toopposite sides of the tank, axle arms secured to said plates andprojecting outwardly therefrom, carrying wheels engaged with said axlearms, and

'hose-con'fining arms formed integral with said plates and. projectingfrom the rear side of the tank between the wheels, the tank beingprovided with a hose-supporting arm or bracket above the said confiningarms.

In testimony whereof I have affixed my base or foot outside I signature,in presence of two witnesses.
